T o all whom 'it may concern.'

Be it known that. we, .YELS P. ALnEiiTsoN and Hannan O. lveiisoiv'," citizens of Denn'iark and the United States, residing at Oakes, in the county of Dickey and State of North Dakota, have invented new and useful Improvements in Shock-Loaders, of which the following'is a. specification.

The invention relates to an improvement in shock loaders, beinggr particularly directed to a construction in the operation of which the shock is picked up, forced lengthwise the machine and :simultaneously elevated and delivered to a laterally operating carrier from which it is discharged into the grain wagon er other vehicle.

The main object of the present invention is the provision of a shock loader in which automatically operating. elevators receive the shock from the pickup and force the same longitudinally of the machine to a A further object ol the invention is the provision of means whereby the travel of the elevator and the degree of Contact lietween the pick-up and the xgfround may he manually controlled hy the operator from his seat, on the machine.

A sill further object of the invention is the provision of a carrier operatingr at right angles to the upper end of the elevating,r mechanism and discharging at :i position to one side of the elevator, so that the shocks carried up in the elevator and deliverl l to the carrier may he discharged h v the latter .into a suitable vehicle traveling with the loader.

The invention will he described in the fol- -lowing specification, reference heilig: had

Fig. 2 is a side elevation of the same, viewed from the discharge end of the carrier. Fig. t

3 is a similar view taken from the opposite side. Fig. 4 is a sectional view through one side of the elevator structure. Fig. 5 is a plan, showing the steering mechanism. Fig. G is a broken elevation, showing a portion of the elevator and illustrating; particularly l, the means for maintaining a proper tension of the drive helt. c Referring particularly to the accompanying drawings, wheiein is shown the preproved shock loader comprises a main frame including side hars 1 and cross bars 2 and 3, the cross bar 2 being arranged at, the forward ends of the side bars and serving as serve as drive wheels for the movable parts,

of the apparatus. lis-ing from the forward ends or the side hars are uprights 10, pref ei'ahl v forwardly inclined with relation to the plane of said hars, and secured to and rising from the side bars near their rear ends are uprights 11 which extend at a right angle to the plane of the side bars. Secured between and to the respective sets of uprights is a platform 12 constituting the main platform over which the shocks are directed in the Aiieeding operation. cured to the inner .surfaces of the respective longitudinallyv alined uprights are upper and lower stringers 11S and 14, the latter being approximately on a plane with the platform l?. and thc former .some distance above the platform. 'lhe .swingers form nii-ans for .supporting guide plates l5 which are duplicated at the respective side edges of the 'nain platform. said side plates extendiner approximately throughout` the length of the platform and comprising metallic sections 1t; secured to the respective stringi-rs and extending aliovc the upper Stringer and having their upper and lower edges bent inwardly, as at 17, to form guide channels 1S on the inner side of and at the upper and lower edges of the ,guide plates. 'l`hat portion of the plates which includes the channels IS? is extended heyoiid the ifesix-ctiveiends of the plates and carried around and outwardly from the guide plates and extended in parallel relation to said guide plates outwardlyy beyond the uprights 10 and 1l. forming guide channels 19, which are in effect a continuation of the guide channels 1S being either formed integrally from and secured in :inv appropriate man- 66 ferred forni of details of structure, my iml ner thereto to provide the continuousl channels. ln bearings 2() secured to the re `the guide channels 1S and 19 during the of the latter. The shaft 32 is driven through -eaeh of which shafts immediately above the :.it their inner ends to clear each other,

speetivel ends of the stringers are mounted upper and lower stub shafts :2l and 22, on

adjacent striiiger is mounted a sprociiet wheel 23. By this construction there is provided at each side of the platform and above the .same guide plates forming continuous guide channels; there being arranged at each end of each guide plate and within the plane of the rounded portieri of the guide channel upper and lower sprocket wheels.

The horizontally alined gears of each guide plate are connected by sprocket chains e-#2.3, the former engaging the upper sprocket wheels of each guide plate and the latter the lower sprocket. wheels. Secured to ,the chains at appropriate intervals are cross bars 2U, which are in ellect comparatively narrow strips of non-resilient metal of such length that upper' and lower ends will be disposed and remain ata-ll times in travel of the chains. To certain of said strips :lo are secured carrier fingers 27, each of which is braced by a strip 28 secured to the. linger intermediate its ends and fixed at its inner end to a strip corresponding in all respects to the strip 26. The fingers are preferably pivotally connected to the strips 2G so as to allow said fingers to accommodate themselves to the movement of the chain, the nornial position of thelfingers in traveling lengthwise the platform being at direct right angles to thegnide plates 1G, The fingers are .so arranged that those on one side ot' the platform will aline transverse the platform with those'on the other side during operation, and are of such length as to just perthereby avoiding the possibility of allowing any material to pass through the fingers in their movement up the platform.

The respective chain shafts 21 are driven from the rear axle in the following manner. 'fi'he upper shafts 2l of each pair are extended below the stringers 14 and each is provived with a belt wheel 29 which is engaged and driven by a belt 30 passing over a Sec-y ond belt. wheel 3l., the respective belt Wheels 31 being secured en opposing ends of a shaft 32 mounted in hearings secured to the lower side of the platform adjacent the lower end the. medium of a sprocket chain 33 engaging sprocket wheels 34 fixed on the shaft 32 and a sprocket 35 fixed on the rear axle, as clearly` shown in 1T ig. 3 of the drawings. The sprocket 35 is preferably carried on one member 3G of a clutch, the opposing member37 of which is keyed to the axle and controlled through a rod 38 leading through intermediate lever connections 39 and rod' 40 to a hand lever'41 extending adjacent the seat 42 of the operator, so that the travel of tlieiingeils lengthwise the platform can be I 1 u l readilycontrolled at the will of the operator. lf desired the sprocket chain 33 may be passed over an automatic belt tightener including an idlei' 43 suspended in a bearing -ontroiled by a spring 44 whereby to take up any slack in the chain.

Secured upon a shaft 45 supported in bearings at the lower and forward end of the. platfornil are pick up lingers 4G, preferably rod like sections curved intermediate their ends so as to present the forward or free ends upon a plane slightly above the surface over which the machine is traveling, the. curvature providing for contact of 4the lingers with said surface at the point in rear of the forward ends, as clearly shown in Fig. 3. An arm 47 is secured to one end of the shaft 43 and connected through the inedium of'a rod 48 with a hand lever 49 also extending adjacent the seat 42, the operation or the lever providing for adjustment of the pick-up lingers at the will of the driver.

Arranged transverse and slightly below the rear or upper end of the platform 12 is Va carrier 50 including a platform 51 sup- Yported on bars extending rearwardly from the uprights 11. The platform 51 oxteiids transverse or across the platform 12, the inner end of said carrier platform terminating slightly beyond the adjacent. side of the main platforn'i while the outer or discharge end of the carrier platform is disposed some. distance beyond the opposing side of the main platform, that is the discharge end of the carrier platform of such distance beyond the adjacent side of the machine as to discharge any material from the carrier platform to one side of and wholly beyond the ope `ating parts of the machine.

The carrier platform is protected by an edge wall 52 open only at the forward or discharge end, said wall being of a height to dispose the upper edge thereof in alinement with the rear or discharge end of' the main platform. as will be clear from Fig. 2. Mounted in bearings secured beneath lthe carrier platform adjacent the respective ends thereof are shafts 53 on each of which near their ends are mounted sprocket wheels 54, as shown. The longitudinally alined pairs of sprocket wheels are designed to carry sprocket chains 55 connected by flights 56, the disposition of the parts being such that the flights are adapted to travel over and in practical Contact with 'the upper surface of the carrier platform. The flights may if ing fingers 57 whereby to more effectively carry the material carried by the main plat forni lengthwise the carrier platform. The carrier platformV is further supported by braces 58 secured to the main structure and one of vthe shafts 53 is extended toward the Adesired be provided with upwardly project- Y,

inain platform and provided with a bevel the opposite. end of which is driver. through a bevel gear U2 meshing with a bevel gear (S3 on lhelower end of one ot' the shafts 32, as clearly shown in Figs. l and Q. By this means it will be noted that as long as the elevating fingers are traveling over the main platform the carrier flights will he traveling over the carrier platform and that any material delivered from the main platform will be deposited in the main carriageand forced lengthwise the saine to a point. of discharge. Preferably l utilize a vehicle, as a wagon, designed' to travel along with the" shock loader and` to receive 1the material delivered from the carrier, as is usual in this type of apparatus. The shaft 32 is preferablg.` mounted in spring pressed adjustable bearings lil-t, wherebyv to permit a yielding of the' belt- 30 in the event inipassahle obstruction met so that danger of breakage of the parts through s'uch obstruction is avoided. The apparatus is designed for propulsion'hy animal power and the latter are connected to the side of the machine. A transversely arranged draft bar G5 is pivotally secured on the main trame and carries swingletrees (Sti at the ends beyond the apparatus. Brace rods 6T are also secured to the side structure of the ra'n'ie and support auxiliary draft rods 638 by which additional animals may be hitched to the macl le if necessary.

The machine is steercdthrough the medium of a steering rod (Si) mounted adjacent the drivers seat and carrying on its lower end a worm T0 designed to drivev a worm gear Tl secure-0l upon one end of a shaft T2 mounted in the side liars l of theanain frame, about which shaftis secured a steering chain 73 terminally fixed th the axle 2 beyond the side liars, the chain being coiled several times ahorn the shaft 75l so that movement ol' the latter under the influence of. the steering rod will turn the axle in the desired direction.

The operation of -the machine will be readily understood from the above description taken in connection with the drawings, it being' obvious that by means of the pickup lingers the shocks are directed onto the main platform, taken '.p by the elevator lingers Q7, forced lengthwise the platform and delivered to the .carrier ,platform from which they are forced laterally into any suitable receiver.

Having thus described the invention what. is claimed as new, is
